For a family of 5 ? you will be spending on basics anywhere from 3K to 5K QR/m, depends also how old the kids are. So, assuming that most of the allowances will eventually be spent, saving 15KQR/month will be very tight.

Besides savings money, you must analyze the other reasons that bring you here? your future fiscal status, resident/non-resident? adventure? are you from this region? are you tired of the West? or of your current job? looking for advancement in your career? do you have a wife or no wife? wife will be staying home? are you gonna own 2 cars?

Is the offer OK ? that is a difficult one to answer when the job description and your credentials are not given.
